HMS Weazel or Weazle was a 16-gun ship-sloop of the Royal Navy, in active service during the War of the Austrian Succession, the Seven Years' War and the American Revolutionary War. Launched in 1745, she remained in British service until 1779 and captured a total of 11 enemy vessels. She was also present, but not actively engaged, at the Second Battle of Cape Finisterre in 1747. Weazel was captured by the French in 1779, and was later sold into private hands.
